COMBINED MIXER AND SL'DGE REMGVER FOR ACETYLENE-GAS GENERATORS.

Original application filed June 6, 1525, Serial No. 35,347. Divided andthis applicati-on filed October 27,

rihis invention relates to an acetylene gas generator, more particularlyto a combined carbide mixer and sludge removing device, and thisapplication is in part a division of our joint application tiled JuneV6, 1925, Serial Number 35,347, and the invention forming the subjectmattei' of this applica tion has for its object to prevent caking andstacking up of the calcium carbide or the residuum or sludge derivedtherefrom within the generating chamber to prevent a sudden rise inpresero:o which is caused by the water breaking through the caked orunslacked sludge, as the preventing of such sudden rise in pressurereduces the possibility of explosion to a niininium.

A further. object of the invention is to provide, in a manner ashereinafter set forth, a revoluble, perforated m ng blade operating onand vthroughout rue bottom of the generator as the carbide is suppliedthereto, and with said blade further operative in a like manner tofacilitate drainage of the generating chamber, as well to facilitate theremoval of the sludge when the carbide feed is shut oli'.

Further objects of the invention are to provide, in a manner ashereinafter' set forth, a combined` mixer and sludge removing device foruse in connection with acetylene gas generators and which is simple inits construction and arrangement, strong, durable, compact,thoroughlyefficient in its use, inexpensive to manufacture, and readilyinstalled with respect to the generator.

iVith the foregoing and other objects in view, the invention consists ofthe novel con' struction, combination and arrangement of parts, ashereinafter more speciiically 'elescribed and illustrated in theaccompanying drawings wherein is shown an embodiment of the invention,but it is to be understood that changes, variations and modificationscan be resorted to which come within the scope of the claims hereuntoappended.'

The blade 54 is otlsubstentiel thickness end height butthe height oiV the blade is less p As illustrated, the bottoni edge otthe blade 54- througliout is ol arcuate contour. Each end ot the bladeis curved to provide a point 65,

which travels the point of joinder between 'thebot'toin 9 end inner'fa-ce of thebody portion 2. rllhe `blede 54: is perforated throughoutfrom the sleeve (S3 to each end and the perlioretions in the blade ere`indicated at 6G. l

TWhen the blade is operated it prevents carbide or the residuuin orsludge derivedV Vtheretrrmi troni celring or stacking on the uppertaceot the bottom 9, and as the blade is perforated, the Waterandeuspended fine. particles oll carbide or residuuin` can pass lil()through the blade during the revolving thereof, and owing to the bladebeing perforated its operating is freer than. would be the case if theblade were not perforated. The blade furthermore operates to facilitatethe drainage of the generating chamber when the carbide feed is shutoff, and also facilitates the removal of the sludge through drainageconnection 8.

rlhe form of the device illustrated in Figures 2 and 3 is of themanually driven type and the blade, which is referred to generally bythe reference character 67, is of the same construction as that referredto in connection with blade 54, and, therefore, it is thoughtunnecessary to specifically describe the blade 67. The body portion ofthe tank is indicated at 68, dome-shaped bottom at G9 and the generatingchamber formed by the tank at 70. Secured within the body portion 68, atthe lower part of the chamber 60 and spaced a substantial distance abovethe bottom 69 is a yoke-shaped bar 7l, extending diametrically from thebottom portion G8 and formed with a centrally disposed opening 7 2 and acollar 7 8 on its lower face and with the opening formed by the collarforming a continuation of the opening 72. Thebar 7l is secured to thebody portion 68 by the hold-fast devices 74. The body portion 68, abovethe bar 71, is formed with an inclined opening 75, and connected to theouter face of the body portion 68 by the hold-fast devices 76 andregistering with the opening 75 is an inclined bearing element 77provided with a packing 78.

rlhe bottom 69, centrally thereof, is vformed with an opening 79 whichaligns with the opening 72, and secured to the lower face of the bottomG9 as well as depending therefrom is a socket forming member 80 whichprovides a bearing for the lower end of the operating shaft 8l for theblade 67. The member 8O is secured to the bottom 69 by the hold-fastdevices 82. The shaft 8l projects slightly above the bar 7l and disposedat an inclination lwith respect to the shaft 7l is a manually operateddriving element S3 therefor. The element 83 extends through the opening7 5 and bearing 77 and projects outwardly from the latter and carries onits 'upper end a handle member 84 therefor. The

inner end of the driving element 83 is connected to the upper end of theshaft 8l by a universal joint 85. The sleeve 63 of the blade G7kismounted on the shaft 8l and interposed between the collar 73 and theupper' face of the bottom 69. The sleeve 63is connected to the shaft 8lby a set screw 64. The blade 67 operates in the same manner as the blade54. The only difference is that the blade 67 is manually driven, whereasthe blade 54 is operated through an elect-rically actuated drivingmechanism therefor.

It is thought the many advantages of a combined carbide mixer and sludgeremoving device, in accordance with this invention, can be readilyunderstood, and although the preferred embodiments of the invention areas illustrated and described, yet lit is to be understood that changesin the details of construction can be had which will fall within thescope of the invention as claimed.

What I claim is l. A combined mixer and sludge removing device foracetylene gas generating chambers comprising a revoluble mixer bladehaving its lower edge extending in the same plane throughout and each ofits ends pointed, said blade formed from a one piece bar-having the topand bottom edges of arcuate curvature and extending lengthwise thereof,said bar of appropriate height, standing on its bottom edge and providedcentrally thereof with an integral vertically disposed hollowenlargement for the reception of the driving means for the bla-de, saidenlargement formed with a lateral opening for the passage of a hold-fastdevice to removably secure the blade to its driving means, and saidblade formed with sets of superposed rows of perforations, each setextending from said enlargement to an end of the bar.
